What's wrong with science education (in Australian high schools)?
Possibly the opinion of those teaching it if this comment by Margaret Shepherd, the president of the Science Teachers Association, is any indication of the thoughts of Australian Science Teachers in general. She said,
“Good scientists require persistence, resilience, being able to do something for a long time without results.”
Persistence ✌
Resilience ✌
Being able to do something for a long time without results?
Really? You think that's what makes a good scientist?
Rather a dispiriting opinion of the work of scientists isn't it? Hardly going to make students leap at the chance of a life dedicated to science if all they're going to achieve is a lifetime of waiting for something to happen.
Is it possible to do "something" in science, and achieve no results ... at all ... nothing .... neither supporting nor refuting a hypothesis?
